DETAILED DESCRIPTION

[0011] The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to "an" or "one" embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

[0012] FIGS. 1 and 2 show an exemplary embodiment of a fastening device for fastening a 3.5 inch first hard disk drive (HDD) 22 or a 2.5 inch second HDD 21. The fastening device includes a bracket 10 and a bottom plate 30. Four locking holes 221 are defined in a bottom surface of the first HDD 22. Four locking holes 211 are defined in a bottom surface of the second HDD 21.

[0013] The bracket 10 includes a substantially rectangular base plate 12. A fastening tab 13 extends out from a first end of the base plate 12. A through hole 131 is defined in the fastening tab 13. Two latching tabs 121 perpendicularly extend down from opposite ends of each of opposite sides of the base plate 12. Two stop tabs 122 perpendicularly extend up from each of the sides and a second end of the base plate 12 opposite to the first end. Four first holes 125 are defined in the base plate 12, respectively adjacent to the opposite sides of the base plate 12, corresponding to the locking holes 221 of the first HDD 22. Four second holes 126 are defined in the base plate 12, corresponding to the locking holes 211 of the second HDD 21.

[0014] FIGS. 1 and 3 show four blocks 32 protruding up from the bottom plate 30. A hooking slot 33 is defined in each block 32, extending through opposite ends and a top surface of the block 32. The hooking slot 33 gradually narrows from a first end of the block 32 to a second end of the block 32 opposite to the first end. A protrusion 34 protrudes up from the bottom plate 30, beside the blocks 32. A mounting hole 35 is defined in a top of the protrusion 34.

[0015] FIGS. 4 and 5 show in assembly, to assemble the first HDD 22, the first HDD 22 is placed on the base plate 12 and abutted against inner surfaces of the stop tabs 122. Four screws 60 extend through the corresponding first holes 125 and then engage in the corresponding locking holes 221. The latching tabs 121 engage in the corresponding hooking slots 33 through the first ends of the corresponding hooking slots 33. A fastener 80, such as a screw, extends through the through hole 131 and engages in the mounting hole 35. Therefore, the first HDD 20 is fastened to the bottom plate 30.

[0016] To assemble the second HDD 21, the second HDD 21 is placed on the base plate 12 and abutted against a stop tab 122 at a corresponding side of the bracket 10. Four screws 60 extend through the corresponding second holes 126 and engage in the corresponding locking holes 211. The second HDD 21 is then fastened to the bottom plate 30.

[0017] The bracket 10 is only fastened to the bottoms of the HDD 21 and 22, occupying a relatively small space, so that the chassis may receive more HDDs.

[0018] Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
